What is the study of inscriptions called ?

Historical evidence is classified into literary sources and archaeological sources. Archaeological sources include epigraphy (the study of inscriptions engraved on stone, metal, or pottery), numismatics (the study of coins and currency), and physical remains such as monuments and artefacts. Epigraphy is especially valuable because inscriptions directly record the names of rulers, dates, land grants, and events, making them a primary source for history.

The question asks which branch of study is defined as "the study of inscriptions." Checking each named field against this definition shows that only one field matches: the branch devoted to reading, decoding, and interpreting inscriptions found on pillars, rocks, copper plates, and temple walls.

• Numismatics is the study of coins, currency, and medals — not inscriptions.

• Palaeontology is the study of fossils and prehistoric life forms — not inscriptions.

• Mycology is the branch of biology dealing with fungi — not inscriptions.

• Epigraphy is the study of inscriptions, which is exactly the definition given in the question — confirming it as the answer.
